Located in beautiful Custer, South Dakota, Ken’s Minerals and Trading Post has been an iconic stop for new and frequent seasonal travelers for over 79 Years. Our store, inside and out, is brimming with thought-proving rocks, rare fossils, beautiful gemstones, hand-crafted jewelry, diverse agates, rare Fairburns, and more.  

For all these years, Ken’s Minerals and Trade Post has been run by our family. We are dedicated to the art of mineral, fossil and rock collecting. Over the past several decades we have amassed a treasure trove of beautiful items, some for sale and some not.
